I have been good friends with someone for a while meeting through mutual friends. We have known each other for about four years. We have discussed lots and shared loads in the past. She shared with me about her previous mental health issues and how she went off the rails in her twenties. Think drugs and sex work. Despite that she has overcome it. And is now a huge success, although she struggles with relationships and has a habit of falling out with people and has never had a stable relationship. We have helped each other out at challenging times in the past couple of years. But all of a sudden she has blocked me on social media and WhatsApp. I have no idea why. So obviously I can't contact her through their. Should I reach out in a different way given her history with friends and cutting them out. I'm a little worried she is on a downward spiral or should I just assume she wants nothing to do with me. I really do care for her
